In this question, we have to write balanced chemical equation for complete combustion of methanol.
00:12
Ch3 -o -h plus oxygen produces carbon dioxide and water.
00:23
Now balance it.
00:25
Here, 3 plus 1, 4 hydrogen atoms.
00:29
So let's put 2 here to balance the number of hydrogen.
00:34
Atoms.
00:36
Now, two oxygen atoms plus two, four oxygen atoms.
00:41
But here, two plus one, three.
00:45
So, we have to increase the oxygen numbers in the reactant side.
00:50
So let's place two here.
00:53
Now, number of hydrogen atoms, three plus one, four times two eight.
01:01
So let's place instead of two, let's place here.
01:08
So hydrogen atoms are balanced.
01:12
Two carbon atoms.
01:14
So let's put two here...
